Including identifiers used in official databases

Is there any work/interest on including identifiers used in official databases (such as eGRID, E-PRTR, and the EU-ETS)? I've worked quite a bit with these databases and would be willing to set up some sort of automated system that could help with the matching process. --ChrisDavis 09:04, 3 February 2012 (UTC)

Need plant:source=* tag

We currently have generator:source=* but no plant:source=* tag. I think it would be very desirable to also have plant:source=*. This would be useful when rendering power infrastructure at lower zooms where you don't want to render individual generators but only the plants as a whole. The value should include the primary fuel(s) used in the power plant, e.g. "wind" for a wind farm or "coal;gas" for a plant having both coal-fired and gas-fired generators. My most recent version of the power rules for Maperitive supports this new tag and shows the usefulness of this tag.

I would like to have comments on adding this tag to the feature page. If there are no serious objections to adding this tag I will include it in a couple of weeks. --opani (talk) 18:36, 21 December 2014 (UTC)

I don't see any objection.
Consistency between generators inside the plant and the plant itself should be considered in QA (like plant:output=* and generator:output=*). Fanfouer (talk) 19:46, 21 December 2014 (UTC)
Passt eigentlich in das System. Nur werden die meisten Kraftwerke mit power=generator gemapped und so kommt auch plant:output=* sehr selten vor.--geozeisig (talk) 08:19, 22 December 2014 (UTC)
I find this misleading. xy:source=* is typically used to indicate the source of an object in OSM (metadata). I understand that it is tried to avoid "combustion" or similar wordings ("fuel") because they don't apply universally (e.g. solar energy, geothermal energy, tidal energy, etc.), but I would recommend to use a different tag, like energy_source=*, power_source=* (i.e, not a colon separated subtag, not referring to plant but to energy/power). --Dieterdreist (talk) 09:28, 16 November 2015 (UTC)
Ok, I didn't see it this way, but I agree with you Martin.
May we use power:input:*=* and power:output:*=* for both plant and generator ?
If not, I think plant:input:*=* will do the trick, won't you ? Fanfouer (talk) 18:27, 16 November 2015 (UTC)
This tag *: source can be confusing, and we have 2 tags (generator: source and plant: source) to say the same thing on 2 different objects, it would be simpler to have only one tag for the 2 (power_source=* ?)

plant:method ?

I think the values of the tag generator:method applies as much to the power plant as to the generator alone. There may be several in a power plant but as for the source. So why not a plant:method=* with the same values as for generator:method.

Energy production

It was possible to indicate the quantity of electricity produced annually. The problem is that it depends on the years. Maybe a tag energy_production = x Wh (or kWh, MWh, GWh) or better energy_production:2015 = *, energy_production:2014 = *, and energy_production:average = *

Don't agree with this. This kind of data should be available in a database outside of OSM. Fanfouer (talk) 18:44, 10 December 2016 (UTC)
Really feel this should be added as an average. All hydro plants here in Norway have a defined average annual production.
Current reference is 1981-2010 and published in 2012. This is updated every 10 years.
The actual production is important as it will also show the efficiency of the plant.
Not many plants reach peak effect often or for very long, at least not hydro and wind. Gazer75 (talk) 17:56, 18 August 2018 (UTC)
I didn't say such information isn't valuable and interesting. But OSM isn't designed to store them as it's time defined data.
A more sustainable way to gather both of static and dynamic data about power plant is to use ref:EU:ENTSOE_EIC=* (for European facilities) and link to external file Fanfouer (talk) 13:19, 19 August 2018 (UTC)
No idea how that works. I can't find anything relating to production values for plants at ENTSOE.
Have a look to their transparency platform Fanfouer (talk) 18:49, 23 August 2018 (UTC)
The average production values change every 10 years so not very often.Gazer75 (talk) 18:59, 19 August 2018 (UTC)
Despite not very often, we may have to update this external data instead of link it with a stable identifier. It's a lot of work for every plant Fanfouer (talk) 18:49, 23 August 2018 (UTC)
The amount of electrical energy produced may depend on the price for which it could be sold. It also may depend if the operator has to switch the generator off for ecological reasons. Those effects are beyond the scope of a map. --Hb 20:06, 11 November 2018 (UTC)
